Open day at the Aldinga Washpool and Blue Lagoon sees attendance of 150 people engaging in Kaurna cultural heritage walks and craft workshops.
Located between Norman Road and Button Road in Aldinga Beach, the Washpool is one of the last coastal lagoon systems in the Adelaide region.
Brenton Grear from Natural Resources Adelaide and Mt Lofty Ranges said the lagoon provided environmental open space for the local community and important habitat for waterbirds.
"The Washpool is also a place of spiritual and cultural significance to the Kaurna People as well as the wider Aboriginal community, with a recent archaeological survey finding that the area is rich in Aboriginal heritage," Mr Grear said.
"The open day helped us in highlighting the importance of the Washpool in terms of its environmental value, its significance to the Aboriginal community and its importance as natural open space.
"Although the lagoon only holds water as seasonal conditions allow, it provides really valuable habitat for waterbirds, including migratory shorebirds, and it's home to 20 plant species that are regarded as rare, vulnerable or endangered."
Kaurna Elder Buster Turner said the Kaurna Nation was honoured to be working with local communities, councils, stakeholders and the SA Government at the Washpool.
"The protection and perseveration of this ancient cultural site, and maintaining and sharing the knowledge of our community is incredibly important to us," she said.
In 2018 a five-year revegetation program for the area was announced by the National Resources for Adelaide and the Mt Lofty Ranges.
